Question

which of the following best describes how the carbohydrate polymer is being built in figure 1? a a water molecule is added to form a hydrogen bond between two monomers. b a water molecule is added to form a covalent bond between two monomers. c a water molecule is removed to form a hydrogen bond between two monomers. d a water molecule is removed to form a covalent bond between two monomers.

Explanation:

Carbohydrate polymers are formed through dehydration - synthesis reactions. In this process, a water molecule is removed, and a covalent bond (glycosidic bond) is formed between two monosaccharide monomers. Hydrogen bonds are not formed during the polymerization process to link monomers into polymers.

Answer:

D. A water molecule is removed to form a covalent bond between two monomers.
